SQL Server 2008 - Getting specific rows like 200-300 - sql

Question

I have a SQL Server table called pluginProspects and I have the following columns..
FirstName
LastName
Email
AmonutOfEmployees
AnnualRevenue
In this table I have thousand of rows, and I wanted to create a SQL statement that allows me to retrieve rows 200 - 300 or even rows 300 - 400 or w/e I want.
I use to use this following code which worked for a while, BUT I want to add specific WHERE clause and its not showing me hundred results, its showing me like 50 or 70 or w/e depending on the results from those specific row numbers
SELECT *
FROM
(SELECT
ROW_NUMBER() OVER (ORDER BY demoID DESC) AS rownum,
demoID, RecordStatus, Email, FirstName, LastName, AmountOfEmployees,
AnnualRevenue
FROM
pluginProspects) AS Salaries1
WHERE
rownum BETWEEN 1 * {STARTNUMBERHERE} - 100 AND 1 * {STARTNUMBERHERE}
AND (RecordStatus = '2014 Lead')
AND (AmonutofEmployees > 10)
ORDER BY
AmountOfEmployees DESC
As you can see {STARTNUMBERHERE} I could put 100, 200, 300, 400 etc to create a paging effect which worked perfectly fine UNTIL I added (AmountofEmployees > 10)
Well in my table there tons of prospects that have less than 10 employees, so this will sometimes only show 10 or 20 results, instead of the first 100 results.
Anyone know the correct way I should be doing this? No I can't use a stored procedure for what I'm trying to do, it has to be pure SQL based

Matt,
Max meant to change it to look like this
SELECT *
FROM
(SELECT
ROW_NUMBER() OVER (ORDER BY demoID DESC) AS rownum,
demoID, RecordStatus, Email, FirstName, LastName, AmountOfEmployees,
AnnualRevenue
FROM
pluginProspects
WHERE (RecordStatus = '2014 Lead')
AND (AmonutofEmployees > 10) ) AS Salaries1
WHERE
rownum BETWEEN 1 * {STARTNUMBERHERE} - 100 AND 1 * {STARTNUMBERHERE}
ORDER BY
AmountOfEmployees DESC
